FLUSHING APPARATUS.

Specification of Letters Patent.

Patented Nov. 18, 1913.

Application filed August 6,-1912. Serial No. 713,668.

To all whom it may concern Be it known that l, HARMON DE LEON Moisn, acitizen of the United States, re-

siding at Sumter, in the county of Sumter and State of South Carolina,have invented certain new and useful Improvements in Flushing Apparatus,of which the follow ing is a specification, reference'being had to theaccompanying drawing.

My invention relates to flushing apparatus such as commonlyemployed forflushing sewers and has for its object the elimination of the floatheretofore employed together with the rubberball controlled outlet valvetogether with the usual by-pass for rescaling the stool when one isused.

My invention also consists more specifically of means whereby the inletvalve is controlled by the movement of the bell which forms an elementof any of the well known forms of air bound siphons.

My invention further results in a greatly simplified structure of fewparts, easy to manufacture in which all parts requiring renewal areeliminated.

The accompanying figure is a sectional view through a flush tankembodying my 7 invention.

While I show but one embodiment it is obvious that same may beconstructed in a different manner without departing from the principleof construction herein claimed as new by me.

1 denotes tank of any suitable structure.

2 is the upper end of the discharge pipe, the lower end of which, notshown in the drawing, being any of the well known siphon forms, thelower end being returned upward to form a liquid trap.

3 is a movable bell attached in any suitable manner to the movable arm4: which is pivoted at 5 to a suitable support 6. The upper extension ofthis arm forms the operating lever 7.

8 is the inlet pipe which enters the valve casing 9 at 10. r

11 is the outlet from the valve communicating with the tank, this beingnormally closed by the valve member 12.

13 is a space over valve 12 and it will be seen that the pressure fromthe supply pipe is always in this space normally thereby keeping valve12 on its seat and preventing the entrance of liquid into the tankprovided the space 14 is also filled with liquid this being accomplishedby providing the bypass hole 15 and channel 16, said channel being in anadjusting screw 17 whereby its area may be varied.

18 is a release valve carried by stem 19 and so arranged that whenpushed downward the liquid in the chamber 14 finds an 7 outlet throughthe opening 20. Stem 19 is suitably connected to the member 1 by meansof a slot 21 or in any other manner whereby it may partake of the motionof member 4. 22 is a small hole in the air bound siphon on aoline withthe bottom of the tank for V vthe purpose of permitting the liquidremaining in the tank below the level of the bell, discharging to forman after flow. If this hole were not provided water would always remainin the tank below the level 28 of the bell.

In operation, the tank being empty, the inlet pipe 8 and chambers 13 and14 are all at the same pressure consequently valve 12 is closed. Handle7 is moved to the dotted position 24 where it is held by spring 25 whichslips over projection 26. This imparts a downward motion to stem 19thereby opening valve 18 and releasing the pressure in chamber 14:. Thepressure of the incoming liquid in 8 and 13 now acts upon the valvemember 27, raises valve 12 from its seat thereby permitting the liquidto enter the tank. When the liquid reaches a height in the tank greaterthan the height of the trapped liquid in the air bound siphon, the tankdischarges. During and especially at the end of the discharge period, astrong downward pull or pressure is exerted on the bell whichaccordingly moves from the position shown in the dotted lines which itoccupies during the filling of the tank, to the position shown in thesolid lines, this downward motion pulling the projection 26 from underspring 25 and at the same time restoring valve 18 to its seat, thisclosing chamber 14. The liquid now passing through the hole 15 reacheschamber 1 1 by way of the passage 16 and when the pressure in 14 issufiicient the valve member 27 is forced downward and the incomingliquid shut off. The liquid remaining in the tank will gradually drainout through the hole 22, the tank remaining entirely empty until againput in operation.

While I have shown but one form of valve, it is obvious that any valveoperating by the release of pressure on one side of the movable valvemember may be employed. It is also obvious that any means of regulatingthe capacity of the by-pass may be employed, also that any form ofactuating mechanism for the bell and valve and any means ofinterconnecting the two may be used.

Having thus described my invention I clai'mz- 1. In a flush tank, aliquid supply, a valve therefor, an auxiliary valve for causing saidvalve to operate, manual means for opening said auxiliary valve, detentmeans engaging said manual means to hold said valve open and means forautomatically releasing said detent and reseating said auxili'ary valve.

2. In a flush tank, a liquid supply, a valve therefor, an auxiliaryvalve for causing said valve to operate, means for opening saidauxiliary valve, detent means for holding said valve open and means,actuated by the discharge of water from the tank, for antomaticallyreleasing said detent and closing said auxiliary valve.

3. In a flush tank, a liquid supply, a valve therefor, means forunseating' said valve to fill the tank, a detent engaging said means toretain the same in a tank filling position and mechanism, operated bythe discharge of'water rom the tank, for releasing said detent andclosing the supply.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.
